Paint protection film (PPF) is a transparent, adhesive-backed urethane film that's meticulously applied to the painted surfaces of vehicles. It acts as a robust barrier against a range of potential damage, from road debris like stones and gravel to scratches from keys or brushes with bushes. This protective layer is designed to absorb impacts and prevent them from marring the underlying paint. While it's virtually invisible once applied, it offers peace of mind to car owners by preserving the vehicle's appearance and value over time.
